Wave Properties and EM Spectrum Review

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a type of wave that consists of oscillating electric and magnetic fields and can travel through a vacuum. Examples include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa. This relationship is described by the equation: Speed = Wavelength x Frequency.

Front

What is frequency?

Back

Frequency is the number of wavelengths that pass a given point per second, measured in Hertz (Hz).

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, organized by wavelength and frequency, from radio waves to gamma rays.

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to examine bones and internal structures due to their ability to penetrate soft tissue.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.

Front

What is the formula to calculate wave speed?

Back

Wave speed can be calculated using the formula: Speed = Wavelength x Frequency.

Front

What is the difference between amplitude and wavelength?

Back

Amplitude is the height of the wave from its rest position, while wavelength is the distance between two consecutive crests or troughs.
